📃 Agenda 📃

19:05 - A message from our sponsor - XM
19:10 - "Testing code in an adversarial setting: a case study" by Vaptistis Anogeianakis
20:10 - Pizza, kindly offered by XM 🍕

🎤 About the talk 🎤
We will dig into a deceptively simple problem: implementing a function to compute N choose K (binomial coefficients). The real challenge isn't the math, it's handling arithmetic overflow correctly.
We will walk through a related problem posted on CodeSignal, the optimal solution the speaker had in mind, the range of solutions submitted by participants, and the custom C++ framework built to evaluate them.

The framework is basically a poor-man's version of the back-end infrastructure powering sites like LeetCode, CodeSignal, and HackerRank. It was built because standard unit and integration testing tools do not address the specific problems that come up when evaluating this kind of solution at scale.

Finally, the speaker will discuss an alternative way of evaluating engineers, in exams, interviews, and similar settings, and more recently, evaluating LLMs. It wraps up with observations from trying this method out on a group of young programmers.

🎤 About the speaker 🎤
Vaptistis Anogeianakis is a senior software engineer and junior inventor.
For the last 6 years or so, he was leading the collection and analysis of telemetry data at the product level at IBM.
Before that, he was designing virtualization management algorithms in Java, crowd-funding the development of his own language, and had spent 10 years developing open source projects in C++.

His interests include computer graphics and programming languages, and he has a patent pending in the virtualization ecosystem.

18:40 - "Local Models 101: Running AI on Your Laptop" by Filippos Karailanidis
19:45 - Pizza, kindly offered by XM 🍕

🎤 About the talk 🎤
You keep hearing you can run AI models on your own laptop — but which models, on what hardware, and how good are they really?

This first edition of AI for Devs Athens is a hands-on primer on running LLMs locally. In 45 minutes we'll go from "what even is a local model" to knowing exactly what you can run on the machine you already own — no cloud, no API keys, no data leaving your laptop.

It's a technical talk, but not a deep one: if you're a curious hobbyist you'll walk out able to download and run your first model tonight; if you're a developer you'll leave with the mental model to reason about size, memory and performance.

What we'll cover:

• What local models are, and why you'd run one on your own machine
• Model size vs performance — and how to tell what your hardware can handle
• The tools that make it easy to get started
• A live demo: running a model from scratch

Who it's for:
developers, tinkerers and hobbyists curious about AI. No ML background needed, you can just show up.

🎤 About the speaker 🎤
Filippos Karailanidis is an AI coach at ByteRail, where he helps companies and professionals adopt AI in their processes. Behind the consulting sits 10+ years of software engineering across frontend, backend and DevOps, and 5 years leading development
teams. He's enthusiastic about the AI ecosystem but still believes vibe-coding must be exercised with restraint. He co-organizes AI for Devs Athens to bring that ecosystem closer to the local developer community.
